APPARATUS FOR USE IN DYEING 0R OTHERWISE ,TREATING WITH LIQUID, FIBBOUSMATERIALS IN SKEINS. r

Application med January 3, 1924. Serial No. 684,128.

To all whom it may comm:

Be it known that I, FREDERICK THoMAs WOOD, a subject of the King ofGreat Britain, residing at Coventry, in the county of Warwick, England,have invented new and useful Improvements in Apparatus for Use in Dyeingor Otherwise Treating with Liquid, Fibrous Materials in Skeins, of whichthe following is a speciication.

This invention consists in improvements in apparatus for use in dyeing,or otherwise treating with liquid, fibrous materials in skeins, theapparatus to which this invention relates being of the kind in which theskeins are supported on rods and other rods have such movem'entrelatively to the rst named rods as to lift the skeins and lower themonto the first named rods.

The object of this invention is to provide apparatus of this kindwith-,means which will mechanically impart to the skeins, in a veryeiiicient and expeditious manner, movements resembling those obtainedwhen manipulating skeins by hand in dyeing, or otherwise subjectingskeins to the action of liquids, the mechanism which actuates thedevices for giving such movements to the skeins being so arranged thatno portions of the mechanism which move in contact with each other arein the bath. A further advantage of apparatus in accordance with thisinvention is that the skeins can be kept entirely immersed in the bathfor any required length of time, and, if desired, until the dyeing iscompleted, which will be particularly beneicial when dyeing with vat, orsulphur, dyes. l

Although the apparatus in accordano with this invention can be used fortreating skeins with liquids other than for dyeing, I will, forsimplicity of description, presume that the apparatus is to be used fordyeing.

According to this invention the second rod, or each second rod, is soshaped, or bent that two portions of thesaid second rod areapproximately parallel to one another and to the stationary rod, thesaid second rod being connected at the end of one portion with means bywhich motion is given to the said second rod such that the other portionhas movement around the first-named rod to alternately lift and lowerthe skeins in the vat.

These and other features of the invention I will describe, withreference to the accompanying drawing, which shows a construction orarran ement in accordance with this l invention which will explain howit may be performed, but the invention is not limited t counter-weightedropes 2, or chains, or other suitable mean, passing over pulleyssupported in any suitable way, a frame consisting of an upper part 3,and a lower part 4, which carries the stationary rods 5, from which theskeins (indicated at 6) are suspended, the said frames being connectedby hollow posts 18. Near to, and above, the lower part 4, of the frameis suspended a beam 7, arranged transversely to, and midway of, thelength of the stationary rods 5, and carrying bent rods 8, correspondingin number to the stationary rods 5, from which the skeins are suspended.The said bent rods 8, extend, in each case, from each side of the beam7, :along parallel, or approximately parallel,VY to the correspondingstationary rod. The said beam 7 is suspended by rods 9, from crank-pins10, carried by discs 11, which can be driven by worm and worm-wheel asindicated at 12, (or other suitable gearing) from an electric, or anyother suitable motor 13. The skeins are suspended in their loweredposition from the stationary rods 5, and the corresponding bent rods 8also pass through the loops of the skeins to lift them from, and lowerthem onto the rods 5.

If desired the lower loops of the skeins can pass round rods 14, carriedby a lower beam y15 suspended from the frame above by counter-weightedropes indicated at 16, (or chains, or other suitable means) which can beattached to the upper ends of guiding bars 17, ixed at their lower endsto the said lower beam 15, and guided in the hollow posts 18, whichconnect the upper and lower parts, 3 and 4, of the frame. These extrarods 14 keep the skeins well down in the dye liquor and, being suspendedas described,

the said rods can be raised when the skeins have become wet enough toremain properly down in the liquor and then the said extra rods 14 willnot interfere with the proper action of the aforesaid bent rods 8.

When the 4apparatus is in o eration with the skeins suspended from t estationary rods 5, and with the bent rods 8 within the upper loops ofthe said skeins, as these bent rods 8 are caused, b the gear aforesaid,to describe circular pat s within the said loops, as indicated by thearrows in Figure 1, the portions of the bent rods 8 extending along oneside of the stationary rods 5, revolve around the said stationary rodsand raise the skeins from oil'l the said stationary rods and bringanother portion, or fresh loop, ol the skeins above the said rods andthen lower this other portion onto the rods 5, and

so on as long as is required, the skeins being consequently practicallyequally submitted to the action of the dyeing liquor throughout theirlength.

The bent rods 8 are shown in different positions in Figures 1 and 2.

-To prevent the skeins from becoming accidentally moved along and fromthe rods the bent rods 8 may be provided with stops 8, (see also Figure3) constituting guards,

these stops, or guards, being preferably arthe upper side of theportions of the said rods projecting from the supporting beam. The saidbent rods 8 are preferably supported from their beam 7 by being providedwith saddle-pieces 8", which straddle the said beam.

If desired, the outer end of each lower rod 14 can be bent downwards inorder to assist in keeping the skeins in their proper position. Agearebox can, if desired, be arranged between the electric motor 13 andthe discs 11 to enable the speed with which the discs are rotated to bevaried as may be required. l

What I claim is 1. Skein treating apparatus, `comprising stationary rodmeans for supporting the skein in a vat, and movable rod means .ro-

tatable around the stationary rod means to alternately lift and lowerthe skeins with respect to said stationary rod means, said movable rodmeans comprising portions parallel to each other and to the stationaryrod means, together with means connected to the movable rod means forcausing portion thereof to travel around the stationary rod means,substantially as described.

2. The combination with the construction specified in claim 1, of meansarranged below the stationary rOd and within the skein loop, for holdingthe skein down within the liquor. i

3.- The combination with the construction specified in claim 1, of meanson the mowable rod for holding the skeins in position thereon. i

4. The combination with the construction specified in claim 1, of meanscompletely and constantly located above the liquor in the vat, forlifting and lowering the skeins and their supports with respect to thevat.

5. Skein treating apparatus, comprising spaced stationary upper andlower members embraced within the skein, together with an `independentmember adapted to travel around one of said stationary members andintermittently engage the skein to cause its step by step displacementaround the vstationary members.

6. Skein treating apparatus, comprising spaced stationary upper andlower members embraced within the skein, together with an independentmember adapted to travel around the .upper stationary member andintermittently lift the skein from said upper member, advance the skeinwith respect thereto and lower the skein upon said member whereby theskein is advanced'step by step around the said stationary members.

In testimony whereof I have signed my name to this specification in thepresence ot two subscribing witnesses.

FREDERICK THOMAS WOOD.
